Claims. (01. 129-1631) 7 This invention relates to paper files and ismore particularly concerned with card indexes and filing elements. It isespecially useful in connection with card indexes of the so-calledvisible type, in which the filing elements are overlapped and haveexposed margins to receive identifications. In many such files, theindex elements are carried by carriers whose ends are received inchannels of a panel, and the present invention deals with filingelements intended to be used in such an arrangement. I

The invention will best be understood by reference to the followingdescription when taken in connection with the accompanying drawings ofone specific embodiment thereof, while its scope will be pointed outmore particularly in the appended claims.

In the drawings:

Fig. l is a front elevation of a card carrier, a a card holder, andcards held by the latter, embodying the invention;

Fig. 2 is a rear elevation of the same;

Fig. 3 is an elevation of a sheet which, when folded, constitutes theprincipal part of the card holder;

Fig. 4 is a sectional view, on an enlarged scale, on line 4-4 of Fig. 1;and

Fig. 5 is a sectional view, on an enlarged scale, on line 55 of Fig. 1.

Referring to the drawings and to the embodiment of the inventionillustrated therein by way of example, there is shown in Fig. 3 a sheetI of appropriate material, such as paper, provided with two tabs 9initially projecting from opposite edges ll of the sheet and hereinconveniently formed as integral parts of the sheet. As herein shown,each tab is in the form of an isosceles triangle, for example a rightangle triangle whose hypothenuse is coincident with the edge H and thetab is foldable along the hypothenuse represented by the broken lineX-X. The sheet is.

also foldable along a line Y-Y perpendicular to the two lines X-X andbisecting the right angles of the triangles.

By folding the sheet first along the lines X-X the tabs are foldedinwardly toward each other, and then by folding the sheet along the lineY-Y, there is formed a fiap l3, and there are also formed a pair ofcorner pockets I5-l5 overlying the front face of the card holder, and apair of corner pockets l|-l'| overlying the rear face of the cardholder, or perhaps more properly the rear, outer face of the flap l3.The corner pockets I5--| 5 receive two corners of a. card 19 applied tothe front face of the card holder, and the corner pockets Il--|'lreceive two corners of a card 2| applied to the rear face of the cardholder. I

The remaining corners and in fact the entire lower margins of the cardsI9 and ii are received;

in a sheath 23 of appropriate sheet material such Celluloid folded (seeFig. 4) topresenta front wall -25 and a rear wall 21. The space betweenthese walls receives the lower margins of the cards l9 and 2| as well asthe intermediate margin of. the card holder 7. In the example shown, thesheath is interlocked with the sheet holder by providing the front wallof the sheath with a downwardly directed lip 29 and by providing thecard holder with a flap it (see Fig. 3) foldable;

along a line z-z and directed upwardly (see Fig.

4:) between the lip 29 and. the front wall 25. The sheath is, of course,applied by sliding the same lengthwise.

The flap 35 may serve to receive identifying matter which will beexposed to view at all times. In the example shown, the flap 3i does notextend the full length of the margin of the card carrier, and thus thereis left a space (see Fig. 1) to receive signal elements or otherappropriate indexing. To prevent the sheath from moving lengthwise,fastening means such as a rivet 33 (see Fig. 5) passes through the frontand rear walls 25 and 21 of the sheath and through the intermediatemargin of the sheet holder 1. As herein shown, the front card I9 isprovided with a notch 35 (see Fig. 1) and the rear card is provided witha notch 37 (see Fig. 2) to receive the rivet.

The sheet holder may be hung upon an appropriate hanger such as a wire39 having terminal enlargements in the form of trunnions M intended tobe received in the channels of a panel and to provide the necessaryoverlap or exposure of the identification receiving margin of the sheetholder. The sheet holder is conveniently supported on the hanger as bypassing the latter through perforations in the former. In the exampleshown, the sheet holder is provided with perforation 4343 between itsedges H and intersected (herein bisected) by the fold line Y-Y, and. itis further provided with perforations 45-45 in the tabs 9 and alsosimilarly intersected by the fold. The two sets or pairs of perforationsare so located that when the tabs are folded inwardly the perforationsof one pair 00- incide with the perforations of the other pair (seeFigs. 1 and 2). To insert the carrier, the flap I3 is folded upwardly,the wire is introduced through the coincident perforations at one end,and is then passed through the coincident perforations at the other end.The flap is then folded down to embrace the wire, and according to thepreferred arrangement the principal portion of the wire is within theprincipal portion of the fold, so that only two small portions of thewire (see Fig. 1) appear overlying the corner pockets l5| 5.

The cards may be employed to receive any desired records, and either orboth sides of the cards may be used. Records might be written on thecard holder, but ordinarily the cards will suffioe.

Having thus described one embodiment of the invention, what I claim anddesire, by Letters Patent, to secure is:

1. A card holder comprising a sheet folded to present a flap overlyingone face thereof, and two tabs initially projecting from opposite endsof the flap and from opposite edges of the sheet and folded to presenttwo pairs of corner pockets, one pair on one face of the sheet.

2. A card holder comprising a sheet having two tabs initially projectingfrom opposite edges of the body of the sheet, said tabs and the body ofthe sheet being provided with perforations andbeing folded along a lineintersecting said perforations, and forming a flap overlying one face ofthe body of the sheet, and said tabs being folded inwardly toward eachother along lines substantially coincident with opposite edges of saidbody to present two pairs of corner pockets, one pair overlying saidflap and the other pair overlying the opposite face of said body, theperforations in said tabs substantially registering with the remainingperforations.

3. A card holder comprising a sheet having two tabs initially projectingfrom opposite edges of the body of the sheet, said sheet being foldedalong a line which extends across the body of the sheet and across saidtabs and forming a flap overlying one face of the body of the sheet,said tabs being folded inwardly toward each other along linessubstantially coincident with opposite edges of said body to present twopairs of corner pockets, one pair overlying said flap and the otheroverlying the opposite face of said body.

4. A card holder comprising a sheet having two tabs, each in the form ofa triangle, initially projecting from opposite edges of the sheet, andwith an apex directed outwardly, the sheet being folded along a lineconnecting said apexes and parallel with a third edge of the sheet, andforming a flap overlying one face of the sheet, said tabs being foldedinwardly toward each other and forming four pockets arranged in pairs,one pair overlying the outer face of said flap; and the other pairoverlying the second face of the sheet.

5. A card holder comprising a sheet having two tabs initially projectingfrom opposite edges of the sheet, each tab being in the form of anisosceles right angle triangle whose hypothenuse is coincident with oneof said edges, and whose right angle is direct outwardly, the sheetbeing folded along a line bisecting the right angles and parallel with athird edge of the sheet and forming a flap overlying one face of thesheet, said tabs being folded inwardly toward each other, each along itshypothenuse, and forming four pockets arranged in pairs, one pairoverlying the outer face of said flap, and the other pair overlying thesecond face of the sheet.
